Description
Technical Field
The invention relates to the technical field of fabric treatment, in particular to a washable, antibacterial and shrink-proof finishing process based on wool/wool blended fabric.
Background
It is well known that the main constituent of wool fibers is an insoluble protein known as keratin. It is made up by using several amino acids through condensation reaction. The wool fiber has natural crimp, the longitudinal surface of the wool fiber is a cylinder which is strongly covered by scales, and the cross section of the wool fiber is approximately circular or elliptical. Due to the existence of the scales, the friction coefficient in the direction opposite to the scales is larger than that in the direction along the scales, and the directional friction effect is called. When the wool fiber or fabric is given damp heat or a chemical agent, the scales are opened, and the fiber keeps the orientation of the forward movement of the root due to the directional friction effect when the scales are repeatedly rubbed and pressed. Thus, the creep of the various fibers with the entangled fibers in a certain direction causes the wool fibers to engage into a felt, and the fleece is tightly shrunk, a property known as felting or felting of wool. The wool fiber has excellent elongation capability and elastic recovery, and can promote the fiber to creep when repeatedly extruded; the natural crimp of wool fibers enables cross-threading of the fibers, which all contribute to felting. The fabric with rich thickness, softness and good heat retention can be weaved by utilizing the felting property of the wool fiber, but the felting property can influence the dimensional stability after washing and is unfavorable for weaving thin fabric with clear weaving pattern. The chemical agent can be adopted to destroy the wool scales, or the resin is coated to make the scales lose the effect, so as to achieve the purpose of fulling. The density of the scale arrangement and the extent to which it protrudes from the surface of the wool have a greater effect on the gloss and surface properties of the wool. The thin wool scales are closely arranged and annularly covered, and the extending end is more prominent, so the thin wool scales have soft luster, large friction coefficient and excellent felting property.
Wool fibers undergo felting shrinkage during the washing process. Because the scales of the wool fibers are arranged in an oriented mode, the forward friction coefficient and the reverse friction coefficient of the scales have a difference value. The wool fiber can produce unidirectional movement when being affected by external force, when the wool fiber is stirred in water, the wool fiber does not move unidirectionally in the same direction, and simultaneously, scale tissues on the surfaces of the fibers are mutually shrunk and bonded, so that the fibers are difficult to stretch, and cannot recover to the original shape, felting and shrinkage are caused, and the shrinkage is irreversible, so that after the fibers are bonded after being tangled, the shrinkage cannot recover.
The chlorination method is to use chlorine or chlorine-containing preparation to carry out shrink-proof finishing on wool fabrics, the process is mature, the effect is good, but a large amount of AOX exists in the treated waste liquid, the COD is high, the serious pollution is caused to the ecological environment, and the damage to fibers is large. Both the oxidation process and the plasma treatment process provide the fabric with a certain shrink resistance, but the effect is not as good as that of the chlorination process. The resin finishing method has good shrink-proof effect, but requires that the resin finishing method can be attached to the surface of the fiber, the dosage is small and uniform, the formed polycondensate is soft, the chemical property is similar to that of wool, and the polycondensate is preferably combined with the wool by chemical bonds. Therefore, the method has great influence on the hand feeling of the fabric and is not suitable for the textile with soft requirement.
For example, patent CN 105926274 a discloses a non-chlorine treatment method of ecological, environment-friendly, healthy, anti-pilling and shrink-proof wool tops, which comprises the following steps: 1 twisting, 2 prewashing, 3 metal treatment, 4 oxidation treatment, 5 alkali treatment, 6 reduction, 7 water washing, 8 acid treatment, 9 softening treatment and 10 drying treatment. Although this patent does not use the oxidation of chlorine based agents to destroy the wool scales, the wool meets the TM31 machine washable standard. However, there are also the following disadvantages: firstly, it carries out preliminary treatment earlier, and flexible processing, then carrying out resin coating and handling, if carry out flexible processing earlier, can make the fibre surface more smooth after the flexible processing, the resin can not be fine when leading to carrying out resin coating again at the back covers on the fibre surface, also can not make resin film layer form continuous rete, finally leads to preventing that the shrink effect is poor. Secondly, in the metal treatment step, the oxidation treatment step, the alkali treatment step and the reduction treatment step, too much oxidant is used, although metal ions can be adsorbed around wool scales to achieve the scale stripping effect, the oxidant can oxidize proteins, and the protein fibers can be unstable.
